The unique nanofiltration concept globally can effectively remove water impurities such as water scale, heavy metals, organic matters and microorganisms.

Hollow fibers offer a larger specific filtration surface area, while internal pressure enables better control over the uniformity of the separation layer and membrane fouling. AQFILM employs a one-step cross-linking reaction with a modified PES support layer to form a charged filtration skin layer. The hollow fiber nanofiltration membranes prepared using this method leverage both "pore size sieving" and "like-charge repulsion" mechanisms to enhance retention efficiency. Compared to spiral-wound structures, these products feature strong source water adaptability, high pure water flux (60-80 LMH@3 bar), high recovery rates, and low energy consumption. They effectively remove water impurities such as scale, heavy metals, organic matter, and microorganisms.
The removal rate of divalent salts can reach 80% to 85%
One-step cross-linked ultra-thin filtration layer with low filtration resistance
Low operating pressure, high flux, and low energy consumption
The recovery rate of a single membrane module is greater than 90%
Ultrafiltration pretreatment can be omitted in some processes
